K3 transmitting in diversity overloads the sub-receiver

[Stan AE7UT]

I'm using a K3 with a sub-receiver, a KPA500, KAT500, dipole and vertical antenna.
I was noticing a clicking noise while transmitting in dual receive and "thought" it was
an antenna switch protecting the sub-receiver.  As most of you know (I didn't) this is
just the sub-receiver overload protection getting too much RF from my transmission.
It took a call to Elecraft's fantastic customer service for me to figure this out.
This only occurs if I use the amp at 500 watts.  Not with barefoot transmitting.

I really like the diversity receive and would like to use it while using the amp.
I know I could probably move the antennas further apart but that's not possible.
Is there another way to fix this?

Thanks for any help you can be.

Hi Stan,

This subject comes up from time to time on the reflector. Here's a link to a previous thread:
